VW Fox TPMS Warning Persists Despite Normal Pressure

Recently dealt with similar sensor fault issues on my 2014 VW Polo TDI. The tire pressure monitoring system started showing incorrect warnings despite proper tire inflation. Using a pressure gauge confirmed all tires were at recommended levels, but the system kept triggering alerts. The diagnostic revealed a sensor battery failure in one wheel. These TPMS sensors have internal batteries that typically last 5-8 years before requiring replacement. The repair involved replacing the failing sensor unit inside the wheel. This meant dismounting the tire, installing a new sensor, and recalibrating the system. While not a major mechanical issue, it requires specialized equipment to program the new sensor to communicate with the car computer. Important to note: Driving with a faulty sensor wont cause tire damage if you maintain proper air pressure through manual checks. However, the constant warning light means the safety system isnt functioning as designed. Based on your Fox age and symptoms, its likely one or more sensors have reached end of life. Have a tire specialist check the sensor battery voltage before replacing any parts.

Thanks for explaining the TPMS sensor replacement. When my flat tire warning started flashing out of nowhere, I initially tried resetting the system and checking air pressure multiple times before realizing it was a sensor issue. Did you remember the repair cost? My mechanic quoted 85€ per sensor which seemed high. Also wondering if youve had any other tire pressure monitoring problems since the replacement? Mine has been working fine for about 6 months now, but sometimes I still double check with a pressure gauge just to be sure. Would be helpful to know if the repair shop needed to reprogram your entire TPMS system or just the individual sensor. The low tire warnings can be really annoying when you know the pressure is actually correct.

After replacing the faulty sensor on my VW Polo, the tire pressure monitoring has worked flawlessly. The total repair cost was 280€, which included dismounting the tire, installing a new sensor, and system recalibration. The garage only needed to program the single new sensor, not the entire TPMS system. Like you, I was initially skeptical after the repair, but the constant sensor fault warnings completely stopped. The air pressure readings now match perfectly with manual gauge checks. The mechanic explained that when these sensors start failing, they typically trigger unusual low tire alerts even when inflation levels are correct. Its smart to verify tire pressure manually occasionally, but you shouldnt need to doubt the system anymore after a proper sensor replacement. If your warning light stays off and the readings remain consistent, the repair was successful. The 85€ per sensor price your mechanic quoted actually sounds reasonable compared to what I paid for the complete service.

Went to the shop last week to fix my tire pressure monitoring issue. The mechanic found the faulty sensor in the front right wheel causing all those false warnings. Cost me 95€ for the sensor plus labor, which seemed fair after comparing prices. The repair process took about an hour. They had to dismount the tire to access the air valve assembly where the sensor sits. After installing the new unit, they recalibrated the system using their diagnostic computer. Pretty straightforward fix once they identified the problem. Been driving for a week now and no more unusual sensor fault alerts or flashing warnings. The speedometer error message cleared up too. Definitely worth getting it properly diagnosed and fixed rather than just living with the constant warnings. Still keeping my pressure gauge in the car just in case, but the TPMS readings finally match what I see when checking manually. Much better experience than my previous mechanic who just kept resetting the system without solving the actual sensor problem.
